Lodgepole synonyms

The mountain valleys are covered with little except grasses; on the higher parts of the mountains there are barren rocks or only a scant growth of timber; but many of the lower mountain slopes, especially those along the western border, are clothed with heavy timber, ponderosa pine, lodgepole pine, Douglas-fir and western larch being the principal species.

The principal trees, after the yellow and lodgepole pines, are the red-fir, so-called hemlock and cedar, the Engelmann spruce, the cottonwood and the aspen (Populus tremuloides).
